Addition and Subtraction up to 100
Addition and subtraction are arguably the most important math
topics for every first grade mathematics student.
The memorization of number bonds and the ‘ feeling’ with numbers
come with the ability to add and subtract numbers without to
much thinking.
Math topics in future school years all elaborate on these important
skills. It might be true that endless pages of number crunching
materials seem to have no meaning to students, but these skills are
so important that we advice every teacher, parent or student to
print this booklet and do all pages! The result will be ta lot of
confidence in math!
This booklet comes with answers and is made for students from
all levels. For the weaker and the stronger! It’s just like a video game;
the more you practice, the better you get!
This booklet is part of our Math in English Skills Series which is
based on core math topics underlying the application of math!
These workbooks, including answers, are free and downloadable

from our website.
